My present invention relates to improvements in windows and particularly to the frame structure and the means for securing the glass panel in the sash. /Vhile I have hereinafter referred to the invention as embodied in a window it'will be'understood that my invention is capable of being emwhere a glass or similar panel is-utilized, and I therefore do not limit the invention to its use ina window.

By the employment of my invention in the window construction the necessity for use of putty in the glazing operationis dispensed with and of course puttying in the process of repairs is also avoided. airtight and weather tight joint is secured between the wood bars of the window, and the glass panel and rattlings of the panel in its seat in the wood bars is eliminated, while at the same time an adequate sealis secured that prevents breaking or cracking 1 of the glass panel edges in the bars of the window. I

In the accompanying drawings Ihave illustrated one complete example of the physical embodiment of my invention, together with slight modifications, wherein the com binations and arrangements of parts of the window are shown, constructed according to the best modes I have thus far devised,

for the practical application of the principles of my invention. V

Figure 1 is a perspective view of awindow sash constructed according to my invention, which may be the lower or upper sash of a double window construction. Figure 2 is a perspective view of the sash of Figure 1 with the upper cross bar or rail and glass panel separated from the remaining parts of the window, as in the course ofconstructing the window.

Figure 3 is a transverse horizontal sectional view at line 3-3 of Figure 1.

Figure 4 is an enlarged detail sectional view showing an undercut groove in one of the frame bars" for the edge of the glass panel. Figure 5 is sectional detail view show- 'ing another form of undercut groove in the frame bar, and a sealing cement or similar composition embedded within theundercut groove andabout the edge of the glass panel.

In the form of my inventionexemplified in the drawings the window is provided with the two side stiles '1 and 2,, the bottom transverse or crossbar 3 with mortised ends 4:, and the top bar or rail 5 also has mortised ends 6. The rectangularglass panel is indicated by the letter G throughout the figures of the drawing and this panel is-first secured in the side rails or stiles 1 and 2 and pushed-down by the use of the top rail 5 as indicated in FigureQ. The upper ends of theside stiles-are fashioned with tenons 7 that fit within'the mortises 6 of the top rail 5. the square or rectangular frame are fashioned with grooves 8 in which the edges of the glass panel G are fitted. V

The upper sash'bar or rail 5 is secured at its ends to the tops of the side stiles by means of dowelpinsS) that are secured in dowel holes 10 in the mortised and tenoned ends of the sashbars, and the sash frame is.

thus retained together in rigid corner joints.

The usual grooves 11 are provided in'the' sldes or outer facesof the side stiles for the sash cords and the stiles, top rail and bottom bar are provided with usual or desired mold or trim.

In Figure 4 one of the sashba'rsas '12 I is shown Wltl'lflll undercut groove 13 for the edge of the glass panel G and the groove is 1 fashioned of such a. size as to necessitate forcing the edges of the panel into the groove thus slightly spreading the clamp beads '14 at the opposite sides of the panel. The wood of 'coursepossesses the required elasticity or resiliency to permit a slight spreading or separating of the two heads and they areclamped with frictional contact against the opposite sides of the glass panel G to form a weathertight seal with a cushioned 7 pressure on the glass that avoids breakage or cracking of the glass. v

In Flgure 5 the sash bar 15 has an undercut groove 16 and a plastic cement 17 or,

other-similar plastic material is injected into the undercut groove to form a filler around the edges of the glass panel and thus provide a weather tight seal as well as an anti-rattling feature for the glass .in its sash frame.

we; f

All of'the bars or rails forming I If'necessary or desirable, the-dowel pins may be removed to permit separation of the top rail from the remainder of the frame,

' and a glass panel may be substituted forthe tion what I claim as new and desire to se 10 cure by Letters Patent 1s In a sash frame the combination with an integral frame member and its glass panel, said member having an undercut groove for the panel with the opening of said groove of less width than the thickness of the glass panel whereby resilient beads are formed at the opposite sides of the panel, and a plastic filter encased within said groove at the edge of the panel. I

In testimony whereof I aflix mysignaturey FRANCIS MpLINDERSMITH.
